Notes:

server; then, disconnect all power cords and external cables.
2. Any system-board switch or jumper blocks that are not shown in the
illustrations in this book are reserved.
v
Power-on password override (switch 6 on switch block 2)
Changing the position of this switch bypasses the power-on password check if
the switch has been moved since the server was last turned on. You do not need
to move the switch back to the default position after the password is overridden.
The default position is Off. To bypass the power-on password check, change the
position to On
Changing the position of this switch does not affect the administrator password
check if an administrator password is set.
v Remove the battery and then reinstall the battery (see “Replacing the battery” on
page 101).
Administrator password
Select this choice to set an administrator password. The administrator password
provides access to all choices on the Configuration/Setup Utility main menu. You
can set, change, or delete both the administrator and power-on passwords and
allow a power-on password to be changed by the user.
Attention: If an administrator password is set and then forgotten, it cannot be
overridden or removed. You must replace the Remote Supervisor Adapter in PCI
slot 1.
